Note:
A new Map Viewer is now available. The new Map Viewer was previously available as a separate beta installation but is now available in the portal automatically. Open it from the app launcher to get started. To learn more, see the new Map Viewer help documentation.
A refresh interval keeps your maps in sync with the latest data while the map is open. For example, you may have an ArcGIS Field Maps map with a damage assessment feature layer that field workers update every few minutes. Set a refresh interval for this damage layer to help your office team see the latest feature data from the field while keeping the map open in their browser, desktop, or device. You can enable a refresh interval between six seconds and one day on many types of layers.
- Verify that you are signed in and have privileges to create content.
Note:
If you do not have privileges to create content, you can still set the refresh interval to explore data by clicking Modify Map.
- Open the map in Map Viewer Classic, click Details, and click Contents.
- Browse to the layer where you want to set a refresh interval, click More Options
, and click Refresh Interval. - Check the Refresh interval every 0 minutes check box.
- Specify the refresh interval for the layer in minutes. The valid range is 0.1 (6 seconds) to 1440 (1 day).
- If you own the layer and want the refresh interval to apply to the layer whenever it appears in a map, click Save Layer.
- Click Save to save changes to the map.
You see any updates that have been made to the data in this layer at the refresh interval you specified.
Considerations for refreshing a layer
Consider the following when refreshing a layer:
- You can enable a refresh interval on the following types of layers: ArcGIS Server web services, hosted feature layers in the ArcGIS Enterprise portal, OGC WMS, OGC WMTS, tile layers, GeoRSS, basemaps (including Bing Maps basemaps), CSV files from the web with latitude and longitude fields, tables, and KML when added to your portal through the My Content page.
- When a layer is redrawn, the layer data is automatically refreshed and the refresh interval starts over. The layer data refreshes again after the specified reset interval has passed or the layer is redrawn, whichever comes first. The layer is redrawn when you pan, zoom, or reload the layer. For KML and GeoRSS, the layer is redrawn when you reload the layer (not when you pan or zoom).
- You cannot enable a refresh interval on a CSV file from the web with address fields (instead of latitude and longitude), map notes, or a file you imported to the map (shapefile, CSV, or GPX).
- Layers only refresh when they are within the visible scale range defined for that layer.
